Their main application is communication with - devices like PROM programmers and ICE equipment. - - It seems that the sections are descibed as being really big, - the example I have says that the text section is 0..ffffffff. - BFD would barf with this, many apps would try to alloc 4GB to - read in the file. - - Tex Hex may contain many sections, but the data which comes in - has no tag saying which section it belongs to, so we create - one section for each block of data, called "blknnnn" which we - stick all the data into. - - TekHex may come out of order and there is no header, so an - initial scan is required to discover the minimum and maximum - addresses used to create the vma and size of the sections we - create. - We read in the data into pages of CHUNK_MASK+1 size and read - them out from that whenever we need to. - - Any number of sections may be created for output, we save them - up and output them when it's time to close the bfd. - - - A TekHex record looks like: -EXAMPLE - %<block length><type><checksum><stuff><cr> - -DESCRIPTION - Where - o length - is the number of bytes in the record not including the % sign. - o type - is one of: - 3) symbol record - 6) data record - 8) termination record - - -The data can come out of order, and may be discontigous. This is a -serial protocol, so big files are unlikely, so we keep a list of 8k chunks -*/ - -#include "bfd.h" -#include "sysdep.h" -#include "libbfd.h" -#include "libiberty.h" - -typedef struct - { - bfd_vma low;
